Molly slammed the crumpled party invite on the kitchen table, her eyes gleaming under the flickering bulb. "Bill, jackpot! Rich kid's birthday bash tomorrow—backyard blowout with a mountain of presents. We're talking iPads, drones, the works!" Bill rubbed his chin, peering at the blurry photo. "Molly, genius, but kids? Screaming hordes? And clowns? I'd rather tango with coppers." "Disguises, dummy! We crash as the magician and his assistant. Abracadabra, poof—gift table vanishes into our van!" Bill snorted. "You in fishnets and top hat? Ha! Fine, but the pony? That nag kicks like a mule. I'll lasso it for cover." "No ponies! We time it for cake o'clock—parents buzzed on punch, brats sticky and distracted. Snag the pile, bounce during piñata whack-fest." Bill leaned in, whispering. "What about the birthday boy? Little Timmy spots us, wails 'Thief!' We're toast." Molly grinned wickedly. "Bribe him with candy from the piñata. 'Shh, kid, Santa's early!' Then we melt into the bounce house chaos." Bill high-fived her. "Love it! Heist of the century—robbing rugrats blind. Tonight, we practice our 'magic' getaway!" "Shh, neighbors! This caper's gonna be a riot." She winked. "Presents for us, tears for them."
